Application september 14, 1949;.seria'1nm115n36 The present inventionrelates to a new and -useful stopper and `measuring-typev vpour-spout for :fluid-containers. The present inventionrelates stillmore particularly to a combination'bottle- 'stopper and pour-spout having ymeans associated therewith whereby a predetermined quantity of liquidwill be measured and dispensed from' the container to which said stopper and pour-spout vare secured when said container is inverted.

Anvobject ofthe present invention is to provide means for dispensing la predetermined quantity of liquid froma container; said measuring means confined wholly within saidcontainer.

:Another kobject `of the present invention is to .provide a metering means for dispensing a predetermined quantity of liquid from ka container, said metering means `supported wholly by the closure` on said. container.

Further objects of the present'invention will befapparentzby referenceto the appendedy specification, 'f claims land drawings.

lFortheipurpose of illustrating the invention, there is :shown in the vaccompanying drawings oneform thereof which isat present-preferred, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that the invention is not limited to the precise rarrangements and f organizations of the instrumentalities asherein shown and described.

"Referring ,to the: drawings wherein ylike referenceicharactersv indicate like parts: -rliigure .1 representsa perspective view Vof a fluid-*container with Athe Vmeasuring-type 4pourspout of the present inventionr operatively secured thereto.

.Figure .2?v represents a vertical:cross-sectional view :of the measuring-type pour-spout-of the 'llinciE--B ofv Figure 2.

` The measuring-type pour-spout of' thepresent invention isa narrow, generally cylindrical tubufs claims. (c1. malts) lar container adapted to t within the bottle of iluid fromwhich predetermined quantities and metered amounts of fluid are to be dispensed. The huid-container or vbottle 20 may be of any customary or standard design, having a neck-portion 2l andan orice or opening 22 therein into which Ya closure or stopper 23 may be frictionally inserted or otherwise held therewithin. To insure a fluid-tight t between the neck 2| and the stopper.23, the stopper may be tapered, as at 24, and may be of any resilient, lcornpressible material .such as `cork `or rubber or synthetic material such as neoprene or4 the like. Instead of a tapered stopper, it is to be understood that a screw-typeclosure may be employed.

The stopper`23 hasr an internal bore 25 therein, adapted to receive a cylindrical -or tubular conduit'26, with thev upper-edge 21 of the tube 2S approximately co-extensive withthe upper edge 28 of the-stopper 23. The upper` end of the conduit 26 may be cemented or otherwise securely held within the `bore 25 of theV stopper 23.

The lower endfof the stopper 23 has a reduced diametered portion 29 thereon adapted to receive and have secured thereto in fluid-tight relationship the upper'end 30 of a tubular chamber 3i. The inner diameter of the tubular chamber 3| is larger than the outer diameter of the inner tube 26, and the shoulder 29 on the stopper 23 holds the tube 26'and the tube 3| in concentric, spaced relationship with each other, asis 'shown in the drawings.

To theupper end of the tube `25,9. pour-spout 32 may 'be secured, 'having a fluid-discharge bore 33E-'andan air-intake passageway 34 therein, both of whichare in communication with the interior ofthe central tube or conduit 25. The pourspout 32 may haveanr angular portion 35 whereby to 'discharge the uid therefrom at an angle to the axis of the bottle to which the stopper and pour-spout arev secured. A cap 36 may be pivotally `secured to the spout 32, as by the prongs 31 (see'Figure '6). The spout 32 is secured to the stopper 23 and to the tube 26 in a duid-tight relationship. The inter-connection between the spout 32, the stopper 23, the conduit 23 and chamber `3| may be other than shown in the drawings. The primary object is to hold the conduit 26 and the chamber 3l in spaced relationship with each other and also using the stopper 23 bothl as a supporting means for the measuringmeans and the pour-spout as well as a closure for the bottle. Thev pour-spout `i12 may be omitted and fthe upper end of the tube 26 extended beyond the surface 28 of the stopper 23.

The outer tube or chamber 3| may be of any appropriate size, being limited only by the inner diameter 22 of the neck 2| of the bottle 20. The wall of the chamber 3| should be thick enough to withstand fluid-pressure and to prevent the deformation of the chamber 3| under constant handling and use. Thus, the diameters and relative sizes shown in the accompanying drawings are merely illustrative and it is to be understood that the dimensions may be varied to suit the appropriate design of any bottle into the orifice of which the measuring-type pour-spout of the present invention will be secured, as well as to permit variations in the quantity of liquid to be metered and dispensed each time the container is inverted. y

The outer chamber 3| may be a single member or may be composed of a number of individual conduits or chambers (as, for instance, the twoL separate units 3 l-a and 3 I-b operatively secured together by the shoulder 3l-c). The use of a plurality of chambers or conduits 3| permits variations in the design of the metering means of the present invention as well as variations in the capacity of the liquid to be dispensed therefrom. However, the chamber 3| may be one single unit of generally cylindrical or tube-like shape having a closed bottom 38 with an open upper end adapted to be secured tothe shoulder-like reduced diametered portion 29 of the stopper 23.

To hold the lower end 39 of the inner conduit 26 in spaced relationship with the inner wall of vthe chamber 3|, a plurality of spacer-members .whereby to direct the liquid into the inner conduit 26 as well as to hold the inner conduit 26 in spaced relationship with the outer chamber 3| Thus, the spacer members 46 and the flared lip 4| serve to support the lower end 39 of the inner `conduit 26 within the outer chamber 3|.

The outer chamber 3| has a liquid outlet port 42 formed near the upper end thereof, below the shoulder portion 29 of the stopper 23, and a second port 43, which may be called an air-inlet port, formed near the lower edge 44 of the inner conduit 26, for a purpose to be hereinafter explained. f

In assembling the measuring-type pour-spout of the present invention, the upper peripheral edge 3|] of the outer chamber 3| may be cemented or otherwise secured to the reduced diametered portion 29 of the stopper 23 with the upper edge 21 of the inner conduit 26 operatively secured and cemented to the inner bore 25 of the stopper 23 and with the lower end 39 of the inner conduit 26 securely held by the spacer members 4D and the flange 4| within the chamber 3|. A neckportion 45 of the pour-spout 32 may be secured within the upper end 2'! of the conduit 26 and cemented or otherwise secured thereto in uidtight relationship. The above assembly comprises the measuring-type pour-spout of the present invention forming the cup-like recess 46 below the lower edge 44 of the inner conduit 26 within the chamber 3|, and the annular space 41 between the inner conduit 26 and the outer chamber 3| above the lower edge 44 of the inner conduit 26 and beneath the stopper 23. The fluid-discharge passageway 33 and the air-intake passageway 34 both form continuations of the not enter the interior of the chamber 3| either through the port 43 or through the port 42 (which are the only means of access to the inside of the chamber 3| from within the interior of the bottle If the liquid level 43 is higher than the opening 43, the liquid will flow into the recess 46 through the port 43 until the liquid level outside the chamber 3| is at the same level as the liquid inside the chamber 3| or until the liquid level 48 in the bottle 2|) falls below the port 43. The measuring-type pour-spout of the present invention may be appropriately dimensioned so that the port 43 will be above the liquid level 48 of each container into which the pour-spout of the present invention isinserted. Thus, the port 43 may be positioned so that no liquid will flow into the recess 46 either through the port 42 or through the port 43 until the bottle 26 is tipped from its upright position as shown in Figure 2.

In order to charge the pour-spout of the present invention and prepare it to deliver a measured quantity of fluid, it is necessary only to invert the bottle 26, as shown in Figure 3. With the bottle inverted, the liquid level 48 will be above the chamber 3| (or at least above the ports 42 and 43) so that the fluid within the bottle 20 may ilow into the space 41 through the port 42, as is shown particularly in Figure 3.

The liquid will iiow into the space 4`| between the inner conduit 26 and the outer chamber 3| until the liquid level 43 within the chamber 3| rises almost to the edge 44 of the inner conduit 26, i. e., to cover the port 43. During the time that the liquid is owing within the space 4'|, the air may be dispelled therefrom 4and bedisplaced through the chamber 46 and out through the inner bore of the passageway 26 and the airintake passageway 34 or the duid-discharge passageway 33. During this flow of liquid through the port42, air to displace said liquid in the bottle is entering through the bore 33 or the passageway 34, tube 26and port 43, and bubbling up through the liquid in the bottle to the air space above the liquid level 48. However, when the liquid-level in the space 4'! rises to the height shown at 49 in Figure 3, the port 43 is closed and no more air can enter the bottle through said port. The air in the bottle above the liquid level 48 then forms an air-lock and stops the iiow of liquid through the port 42. Of course, this air-lock is equally effective to keep liquid from flowing through the port 43. Thus, the liquid will not rise any higher than the position shown in Figure 3.

During the rst inversion of the bottle, as above described, no fluid will be discharged therefrom inasmuch as the recess 46 has no uid therewithin.

When the bottle is placed right-side-up (after its iirst` inversion) the liquid which illed the space 41 now ows downwardly within the chamber 3| and collects within the lower cup-shaped recess 46 thereof, as is shown in Figure 4. If'the liquid within the space 4`| is of greater volume than thecapacity of the cup-shaped recess 46,.

the'excess vmay flow outwardly within the'bottle 2|] throughv the. port 43. 111 the quantityzof 'liquid scoopedaup by the flared up trof theconduir 26 and discharged therefrom through the fluid discharge passageway 33. Atvthe Sametime that the fluid is being discharged from the cup-shaped recess 46, a new supply of'liquid is being metered andmeasured within the space 4,xasis shown in Figure 3. Thereafter, eachinversion'and repositioning oiathe bottle in an upright position will dispense a metered quantity yof fluid from the bottle aswell as measure another equal quantity thereofand place it within the cup-like recess 46 of the chamber 3l in preparation for the next inversion of the bottle.

.lt is obvious that the capacity ofthe space 47, as shown particularly iny Figure 3,n1ay` be varied by proper selection of the inner conduit 2B` and the outer chamber 3l so that an appropriate and predetermined volume of vfiuid "may be measured therein. Thus, we prefer that the quantity of fluid measured Within the passage- .way 4! be equal to a fjigger or the like, which is approximately one and one-half iuid` ounces andwhich is 1customarily the amount of liquid dispensedfrom a liquor bottle by. a taproom owner or .a bartender for each single drink of liquor. However, the capacity of the space42' may be varied sothat anysdesired quantity ci fluidinay be dispensed or measured therewithin.

Similarly, the location ofthe port 43 `and the length of the inner conduit it may be changed and thus permit more (or less) luidto be meas# ured or metered within the space 4l".

Likewise, `the port 43 may beappropriately placed along theA outer surface of the chamber 3l so that the liquid retained within the cupshaped recess 48 thereof (upon setting the bottle upright) will be equal to the desired quantity of fluid to be dispensed on the next inversion of the bottle.

It will be notedthat the scoop` portion 4l `of the inner conduit 26 4engages .the inner Wall of the outer chamber 3l at thesame side ofthe axis thereof as that toward which the discharge bore curved in the stopper 32. This is 4advantageous because it influences the user to tiltor .turnthe bottle, when inverting' it, totliatsde, i.,e., through a clockwise turning direction as viewed in Figure 4, which will cause the scoop toact most efciently in receiving liquid from the recess 46 and conducting it out through the inner conduit 2% rather than into the space 41, into whichlsome of the liquid would pass if the bottle had been turned in the opposite direction.

Although we have shown only two ports 4Z and 43 offering communication between .the interior of the chamber 3i vand the interior of the bottle 2t, any appropriate number of ports or apertures may be placed therein at the `approximate level or position shown with` respect .to the ports i2 and 133 so that the fluid will pass quickly from one chamber `to another Without causing any :bubbling or turbulence therein and without causing the operatorofthe present invention to wait undulyvlong 'for the *nuid' to :iicwfrom one chamber tothe other. `The'present invention may 'be yembodied lin other speciiicforms without departing'from the spirit Aor essentialattributesthereoffand'it is therefore desired that the vpresenty embodiment be considered inall-respectsN as illustrative and not restrictive, lreference being hadto the.` appended claimsy rather than to theforegoingdescription to indicate thel scopeof the invention.
